飞凌2440开发板在挂载SD卡（2G）时出现如下错误：插上SD卡时，超级终端显示：
# mmc0: host does not support reading read-only switch. assuming write-enable.
mmcblk0: mmc0:aaaa SD02G 1931264KiB
/dev/mmc/blk0:<3>mmcblk0: error 2 transferring data

当输入挂载命令时显示：

当我换成1G的MMc卡时，插上后，超级终端根本一点反应也没有，在dev目录下没有mmc文件，各位给说说，是怎么回事啊

你用的哪个内核？

    2.6.18内核的啊，板子自带的，在wince下就能读写操作!
